Rancang Bangun Miniatur Sistem Monitoring Stock Barang Menggunakan Sensor Load Cell Dan Sensor Ultrasonik Berbasis IoT
No full textBisnis apapun yang ingin beroperasi secara efisien harus memiliki pemahaman yang tepat tentang persediaan stok barang di gudang. Pemeriksaan stok barang di setiap gudang perusahaan adalah hal yang wajib dilakukan. Ketika tingkat persediaan di perusahaan manufaktur rendah, stock opname dapat membantu perusahaan mengisi kembali persediaan atau membuat pesanan baru dengan segera. Hal ini juga dapat membantu gudang memperkirakan berapa banyak persediaan barang atau bahan baku yang mereka miliki. Namun, secara umum, setiap bisnis melakukan penghitungan stok secara manual, yang mengharuskan karyawan menghitung setiap barang saat dibawa ke gudang satu per satu. Hal ini tentu saja membutuhkan banyak tenaga dan waktu. Dengan menggunakan alat ini, penghitungan stok barang dapat dilakukan dengan lebih cepat dengan jumlah karyawan yang lebih sedikit. Pengoperasian alat ini mengandalkan penggunaan sensor ultrasonik dan load cell yang masing-masing dapat mengidentifikasi persediaan produk. Data yang dikumpulkan setiap sensor akan diteruskan ke NodeMCU ESP8266 untuk diproses agar dapat dikonversi. Hasil pengujian menunjukkan bahwa ke dua sensor berbasis IoT yang digunakan dalam sistem pemantauan stok dapat menampilkan data secara realtime yang dapat dilihat secara online. Kesalahan pembacaan sensor load cell yang dikonversi ke dalam unit (ea) adalah 0%, sedangkan kesalahan pembacaan sensor ultrasonik yang dikonversi ke dalam volume (ml) adalah 5,5%.

Desain Sistem Kontrol Backwash Filter Air Menggunakan Arduino Nano Dan Bahan Daur Ulang
No full textSistem kontrol backwash filter air daur ulang berbasis Arduino Nano dirancang untuk mengatasi masalah yang biasa dihadapi dalam pengoperasian sistem instalasi pengolahan air limbah (IPAL), yaitu kurangnya pekerja tetap untuk mengoperasikan peralatan, khususnya sistem backwash. Sistem backwash dirancang untuk mengoptimalkan umur panjang filter air yang dipulihkan. Prototipe sistem kontrol backwash filter air daur ulang dikembangkan dengan menggunakan Arduino Nano sebagai mikrokontroler dalam penelitian ini. Sistem kontrol backwash filter air daur ulang bertenaga Arduino Nano dirancang khusus untuk mengatasi tantangan operasional yang sering terlihat pada sistem instalasi pengolahan air limbah (IPAL), termasuk tidak adanya personel permanen untuk mengelola peralatan, khususnya sistem backwash. Sistem backwash secara khusus dirancang untuk memaksimalkan masa pakai sistem pemulihan air yang disaring. Dalam penelitian ini, para peneliti membuat prototipe sistem kontrol backwash filter air daur ulang dengan menggunakan Arduino Nano sebagai mikrokontroler. Berdasarkan hasil pengujian peralatan, telah ditentukan bahwa sistem kontrol memulai sistem backwash berdasarkan instruksi terprogram yang dibuat menggunakan Arduino IDE. Sistem kontrol mengaktifkan sistem backwash selama 262 detik. Selama jangka waktu ini, sistem backwash, yang meliputi solenoida 1 dan 2, beroperasi secara bergantian. Solenoid 1 dihidupkan selama total 30 detik, diikuti oleh solenoid 2 yang dihidupkan selama 20 detik. Ada penundaan 3 detik di antara setiap periode penyalaan, dan jeda 10 detik di antara aktivasi solenoid 1 dan solenoid 2. Diawali dengan setelah pompa filter aktif, maka akan mengirimkan trigger ke dalam sistem dan akan diterima oleh timer yang akan mengirimkannya ke Arduino Nano sebagai input, Setelah Arduino Nano menerima input maka rangkaian program yang telah dirancang akan aktif, Arduino mengeluarkan output ke relay 1 dan 2, dimana relay 1 dan 2 akan menyala bergantian dan Relay 1 akan menyala sebanyak tiga kali. hasil perancangan wiring peralatan elektrik yang terdiri atas Arduino Nano, adaptor, relay dua channel, relay, timer, solenoid valve, lampu indikator hingga busbar
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
